| USES Karnak
Metal Seam Sealing Tape is designed for sealing horizontal and vertical
seams on properly prepared metal roof surfaces. Its ease of use
allows for quicker installations than traditional sealing materials.
Coating applications can take place the same day, also speeding
system installations.
ADVANTAGES
- Correct protective mil thickness every time.
- Solvent-free.
- Superior adhesive bond that remains flexible.
- Forms a durable, weather resistant rubber bond.
- Allows coating applications to start that same day.
- No drying time required.
- Save 50% in material and labor costs to seal seams.
SURFACE PREPARATIONAll
surfaces to be sealed must be clean, dry and free from oil, grease,
dirt, dust and other foreign matter.
APPLICATIONAfter
surfaces have been properly prepared, apply Karnak Metal Seam Sealing
Tape to the roof surface exactly the first time. Trying to remove
may damage seam sealing tape and roofing. Do not stretch. Press
down firmly starting at the center and working towards the outside
edge, removing bubbles. Slight wrinkling should not affect performance
of seal. Edges must be free of fishmouths, uplifts and tunnels.
Finish seam by applying 502 Seam Sealer, 505 Seam Sealer or 229AR-Elatomeric
over the taped seam. Using a brush or roller, apply seam sealer
at a 1/16” thickness to completely cover seam sealing tape
and feather out 2”. Allow to cure 24 hours.
